Also will commit to 1 of each kit! Thanks!

It might be interesting if someone would work up a test jig for evaluating and stress-testing the "WX" series of amplifier chips. Could be revealing to see just what the failure mode really is. Arv

Hi Dave, Thats it uBitx.. this group deals with Bitx20/40/u with different circuits! Raj

provided 1. you don't plug a mono head/earphone plug and 2. try working at lower volume levels, even WX make should try to work Safest appears to introduce 7806 for the TDA chip alone. You can ssee

I see that the ubitx uses a 10k pot for the volume but I can’t seem to find a good knob for it. I do however have a 4.7k pot with a switch that has a more standard shaft size. Would I experience any

Raj, I am not sure what you mean by avatar. It is the uBITX...is that what you are looking for? Dave

I am still working on my mic. I don't get enough umph from it. I'll try a voice cq. Should we agree on a freq for cw qso's? 7030 khz works for me. I'm aware I can do cw anywhere my license allows.

Well, I got my uBITX working just fine for me and decided it was a keeper, so I ordered some TDA2822 spares on Ebay and they came a couple of days ago, maked with the dreaded "WX". ?The part which

My guess would be $18 postage plus or minus $5? Bill Maxwell on Tasmania has ordered several times. He is way out in the "Boonies", takes about a month to get to him. Here is some documentation. TNX

I'm also really curious about an inexpensive VHF/UHF MMIC. Searching around "BGA" takes me to NXP which has a wide selection of parts, but no hits for BGA591 -David [email protected]> wrote:

Soon as the order of MPSH10s show up I will be trying them. In the mean time when pain subsides from putting up the vegetable garden I have BF106s to try for Q90.? and maybe also the pre-driver.

Joe I loaded Roger Clarks bootloader on one of the pills and it is working OK just on usb. A little off topic but I ordered one of the 400 encoders that I think is like the one you got, by the picture

I am curious if anyone has looked at the shape of the CW waveform generated by the BITX40 using the CW Carrier Mod associated with PE1NWLs Bitx40 sketch ? CW-CARRIER wiring.png? (

I have an idea but which board avatar is this? Raj

I just received my ubitx and got it up and running, I am noticing that when turned on with the volume as low as it will go their is a lot of noise coming through the head phones. I hope that some of

Ok, thanks all. I checked the pins on the connector. I also got rid of excess wiringing and resoldered the yellow orange and green wires to the audio jack. None of that helps. What I did find by

Thanks Daniel, I'll explore what you tried.? I've had a little time to start looking at the CEC firmware code. He has a number of additional "switches" in the code regarding CW that are not in the
